Abstract

The invention relates to a rotating nozzle structure of an extruder which comprises a rotatable nozzle, a die, which rests against the extruder frame and which comprises an annular front surface on the nozzle side, and a sealing plate, which is arranged between the front surface of the die and the nozzle and pressed tightly against the sealing surface of the nozzle to seal the nozzle with respect to the die. According to the invention, the die is arranged to slide in the axial direction with respect to the extruder frame and comprises a flow channel, which is under pressure of the material to be extruded and tapers conically towards the nozzle, and that the ratio of the area (Atiiv) of the die's annular front surface to the area (Aproj) of the projection surface of the flow channel's conical section is between 0.1 and 10.
